DOI: 10.1088/1361-6463/ae1487
Abstract: Micromagnetic simulations demonstrate that in a nanometer-thick magnonic crystal made of ferrite, the width modes split into fundamental and additional submodes. The influence of the ridge/groove width ratio on the energy interaction between submodes, dispersion… read more here.

DOI: 10.3390/nano12213838
Abstract: A nanostrip magnonic-crystal waveguide with spatially periodic width modulation can serve as a gigahertz-range spin-wave filter. Compared with the regular constant-width nanostrip, the periodic width modulation creates forbidden bands (band gaps) at the Brillouin zone… read more here.
